If tir ep ressure of 20 0k Pa (2.0 ba r/ 29 psi )h as
bee na chieved after am aximu mp eriod of ten
minutes: X
Switch off the tire inflation compressor. X
Unscrew the filler hose from the valve of the
faulty tire. X
Stow the tire sealant bottle and the tire infla-
tion compressor. X
Pull away immediately .X
Stop after driving for approximately ten
minutes and check the tire pressure with the
tire inflation compressor.
The tire pressure must now be at least
130 kPa (1.3 bar/19 psi).
G WARNING
If the required tire pressure is not reached
after driving for as hort period, the tire is too
badly damaged. The tire sealant cannot repair
the tire in this instance. Damaged tires and a
tire pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is ar isk of accident.
Do not continue driving. Contact aq ualified
specialist workshop.
i In cases such as the one mentioned above,
contact an authorized Mercedes-Benz Cen-
ter. Or call 1-800-FOR-MERCede s( in the
USA) or 1-800-387-0100 (in Canada). X
Correct the tire pressure if it is still at least
130 kPa (1.3 bar/19 psi) .S ee the Tire and

To increase the tire pressure: switch on the
tire inflation compressor. X
To reduce the tire pressure: depress pres-
sure release button C next to pressure
gauge D . X
When the tire pressure is correct, unscrew the
filler hose from the valve of the sealed tire. X
Screw the valve cap onto the tire valve of the
sealed tire.
X
To remove the tire sealant bottle from the tire
inflation compressor, press together the lock-
ing tabs on the yellow cap. X
Pul lt he tire sealant bottle out of the tire infla-
tion compressor.
The filler hose remains attache dtot he tire

Drive to the nearest qualified specialist work-
shop and have the tire change dt here.X
Have the tire sealant bottle and the filler hose
replaced as soon as possibl eataq ualified
